Patches gitea admin credentials into secret/sol for Sol's Gitea
integration. Adds sol-agent vault policy with read/write access
to sol-tokens/* for user impersonation PATs, plus k8s auth role
bound to the matrix namespace.
Adds Verb variants: auth, vcs, chat, search, storage, media, mon,
vault, people, docs, meet, drive, mail, cal, find. Each delegates
to the corresponding SDK cli.rs dispatch function.
Removes the legacy `user` command (replaced by `auth identity`).
Renames Get's -o to --kubectl-output to avoid conflict with the
new global -o/--output flag. Enables all SDK features in binary.
Convert the single binary crate into a Cargo workspace with two members:
sunbeam-sdk (library) and sunbeam (thin binary). Moves build.rs to the
SDK with adjusted .git/HEAD path for the nested layout.
